An estimate: the size a Balanced copy would have at the chosen resolution. The real size shows when you compress.
This browser can’t compress video yet. It needs WebCodecs, which recent Chrome, Edge, Safari and Firefox on a computer have. Firefox on Android doesn’t. Try another browser, or use the photo compressor.
Short answer
Compressing videos does save space, because videos are usually the largest files on a phone. A minute of 1080p iPhone video is 70–105 MB, according to Apple, and a Balanced copy of it is about 41 MB, a saving of 42–61%. Choose your videos above, as many as you like, and the page adds up how much space they would free at the resolution you pick. It only reads each video’s size, length and picture: nothing is compressed or uploaded to a server.
How to see how much space you would save
-
Choose your videos
Pick as many as you like from your photo library or your files: there is no limit, and it is free. MP4, MOV, WebM and MKV open. Video from an iPhone is often HEVC, which opens in Safari or a recent Chrome or Edge. A video your browser cannot read is listed and left out of the total.
-
Pick the resolution
Auto keeps the picture at up to 1080p. Up to 720p and Up to 480p give smaller copies still. Each choice is a ceiling: a video below it keeps its own resolution. The estimate changes as soon as you choose.
-
Read the saving
The big figure is the space all your videos would free, with the percentage. The table lists each video: its size now, its size after and how much is saved. After is the size of a Balanced copy, which sets no size target and keeps up to 30 frames per second. It is an estimate; the real size shows when you compress.

How much space a minute of video frees
Do videos take up a lot of space on iPhone? A minute of 1080p video is 70–105 MB, according to Apple, so a few long clips add up fast. The table shows what one minute becomes with each Resolution choice on the Balanced plan, and how much of it you save. The saving is a range because Apple’s figure is a range.
| Resolution choice | One minute becomes | Space saved |
|---|---|---|
| Auto (up to 1080p) | About 41 MB | 42–61% |
| Up to 720p | About 19 MB | 73–82% |
| Up to 480p | About 9 MB | 87–92% |
| Auto, from 4K at 30 fps | About 41 MB | Down from more than 175 MB, according to Apple |

Questions about video and space
Does compressing videos save space?
Yes. Compressing makes a new file with less data for every second, so it is smaller: a Balanced copy is about 41 MB a minute, against 70–105 MB straight from an iPhone at 1080p. The space comes back when you keep the smaller copy instead of the original, and that is always your decision: this page never changes or removes a file.
Do videos take up a lot of storage?
Yes, more than most files. According to Apple, a minute of 1080p iPhone video is 70–105 MB, and a minute of 4K at 30 fps is more than 175 MB. Ten minutes of 1080p video come to about 700 MB to 1 GB. The video size calculator shows the size for any length.
Why are iPhone videos so big?
A phone records every second at high quality, with a lot of data for each frame, so even a short clip is large: 70–105 MB a minute at 1080p, and more than 175 MB at 4K. Compressing lowers the data for every second. A Balanced copy keeps the picture at up to 1080p and brings a minute down to about 41 MB.
Why are my iPhone videos taking up so much storage?
Because they add up: a minute is 70–105 MB at 1080p, so a library of long clips reaches many gigabytes. If iPhone videos are taking up space, start with the longest, because size grows with length. Add your videos above and the table shows each one’s size now and after compression.
iPhone storage full: where do I start?
Videos are usually the largest files on a phone, so start with them. Add your videos above to see how much space a smaller copy of each would free.
How to make a video take up less space?
Compress it. Choose Up to 720p or Up to 480p for a smaller copy still: a minute comes to about 19 MB or 9 MB, against 41 MB at Auto. The picture gets softer as it gets smaller, and the estimate shows each saving before you compress anything.
Will a smaller video look worse?
A little. Every compression discards some detail, though at Auto the picture stays at up to 1080p, where the loss rarely shows on a phone screen. The page video compressor without losing quality explains how to keep the loss small.
Is my video uploaded when I check the space?
No. The page only reads each video’s size, length and picture, in your browser, on your own device. Nothing is compressed, and nothing is sent to a server. You can check in the Network tab of your browser’s developer tools.
